4 claims. (ci. 10i- 176) This -invention relates to improvements in aprinting press and is particularly applicable when employed inconnection with a high speed press Asuch as used by most metropolitannewspapers.

The principal objects of the invention are to provide a press whichoperates at high speed with means contained within itself for preventingthe ne mist of ink which, by the action of centrifugal force, is apt tobe distributed by such a press, from being thrown outside the presswhere it can do any damage; to make the inking mechanism and printingcouple readily accessible to facilitate adjustment, moving of rollers orcleaning; to construct a press of this typein which the arch is formedas usual and the inking system constitutes the sides of the arch; tolocate the ink reservoirs or fountains in the lower end of this arch atthe sides approximately at oor level; to guide the web through the pressin -such a manner that it will not be affected by the ink fog; to makethe press easily accessible for reaching the web and allow the pressmanto reach various parts of the press readily; to arrange the fountainregulating keys at a suicient height to permit adjustment without thenecessity of reaching downto the press floor or reaching down unduly; toprovide access to the main fountain keys so that sections of them can beremoved; to permit application of a special color fountain, and toprovide the press with a cover employing a part of the press frame tocooperate therewith which will effectively enclose, not only the press,but particularly the inking mechanism and yet provide such cover withdoors to make the parts accessible for adjustments and the like.

Other objects and advantages of the invention will appear hereinafter.

'Ihe invention is shown as applied to a high speed newspaper printingpress of the type in which the press isarch-like in end elevation andthat is the type of press to which this invention is particularly, butnot exclusively, adapted. At the speed developed by such a presscentrifugal force overcomes the surface tension of the ink to a certaindegree and a mist or fog is produced, especially in the lower section ofthe inking mechanism. It is partly to avoid injury to the web by thisfog and the spreading of the fog outside the press that several of thefeatures of the invention are employed. The type of press shown receivesthe web W from below and it is threaded between the two inkingmechanisms and through the rolls of the printing mechanism, in' themanner shown, being discharged near the top.

In Figs. land 2, a thin metal guard or cover I is made to coincide withthe outline of a press side frame 2 to effectively conceal the ends ofthe plate, impression cylinders, and the ink drums, or anything attachedto said parts. Referring particularly to Fig. 5 for a clearer diagram ofthis arrangement it' will be noted that the press side frame is carvedor hollowed out to accommodate various parts within the depressions.

A plate cylinder 3, which is rotatably mounted in the side frame 2 bybearings 4, is driven by a gear 5 which is attached to the end of thecylinder 3 and is within the hollow of the frame 2.

Ink drums 6, 1 and 8 are carried within the frame 2 by bearings 9, I0and II in such manner that they can be moved longitudinally as well asrotated. Fig. 5 shows that the mechanism which causes the ink drums tobe moved longitudinally is carried inside of a hollow of the frame 2.

'I'he cover I seals the above mentioned parts within the frame'2, makingan oil tight arrangecylinder and ink drums is constructed in like mannerto accommodate any parts attached to said cylinders or drums.

A cover of this design has an arched opening beneath the press. Toenclose this portion of the machine, hinged doors I5 on the press driveside, and hinged doors I1 on the end of the press opposite to the drive,are used. Said doors are hinged by hinges I3 to the cover I and suitablyshut olf this space on both ends of the press unit, but at the same timemake it possible to reach parts inside of the unit. Figs. 1, 6 and 'Iillustrate the.

with the cover on that end of the press. Handles 23 secure the doors I1in place.

The right and left hand sides of the press, as shown in Fig. 1, areconstructed in a similar manner so that the description of one side willserve for both. Fig. 1 shows that the guards extending from the floor toa point over the plate cylinder 3 are made in a. number of sections.

A stationary cover section I3 supports a plurality of fountain bladeadjusting screws 23 and keys 25 and covers the lower outside part of theink motion. These screws adjust fountain blades 24. Said section is heldin position by a channel 23 secured to the side frame 2 by a bracket 21.Said channel protects the keys 25 of the adjusting screws 23 which areplaced in a reasonably high position, thereby eliminating the necessityof bending very far down to make adjustments.

Connected by hinges to the top of the same channel is a section 29 thatmay be opened downward to make the upper part of the ink motion and partof the plate cylinder accessible. The section 23 is held in position bypins 33 and 3| that are accommodated by suitably drilled holes in theside frame 2, as best shown in Fig. 4.

A spring 32, abutting against a bracket 33 secured to the guard section23, pushes against a collar 34 on the pin 33, thereby causing the pin 33to remain extended beyond the guard. The same construction is used onthe pin 3|. Manipulation of a handle 35, Fig. 2, pivotally mounted onthe inside face of the section 23, will cause links 36 and 31 towithdraw the pins 33 and 3| respectively and allow the guard section 23to be opened and lowered.

When the section 29 is in closed position it becomes a support for thesection 33 that covers the plate cylinder 3.. The section 33 is carriedat the upper end by hinge studs 33 resting in brackets 43 secured to theside frame 2. Said hinge stud will allow the section 33 to be raised bypivoting upward, allowing the pressman to reach the plate cylinder 3.

'Ihe sections I9 and 29 allow easy access to the distributing rollsurfaces, both for roller adjustment and removal. The door 4I which ishinged to the cover I at the end of the press, is swung outward toexpose the roller ends and sockets in which rollers rotate. Said door issecurely fastened in position by a locking handle 42 which engages withthe bracket 21.`

It is now vident that the guards, covers and doors cooperate in makingthis press completely enclosed. The openings at both ends of the unitare closed up, and the outside of the press is covered from the floorline to above the plate cylinders. The arrangement of the guards willeliminate all ink fog from the press room and allow the pressman tocarry on his work on the machine efficiently.

It will be noted that a ductor type fountain is used. A fountain roll 5Iin a fountain bowl 52 is partially submerged in ink and is rotatedtherein accumulating a supply of ink on its surface. A ductor roll 53,which is oscillated back and forth between the fountain roll 5I and inkdrum 3, is rotatably mounted at the end of lever arms 54.

When the ductor roll 53 is placed against, the fountain roll 5I, anaccumulation of ink will be picked up which will be deposited on the inkdrum 3. The ink drums 1 and 3 are arranged with a plurality of transferand distributing rolls in such a manner that a thin film of ink iscarried to form rolls 53 and 59 which are in contact with printingplates carried on the plate cylinder 3 and will transfer to the plateson said cylinder a sufficient quantity of ink to produce a properly`printed page.

The fountain roll 5| picks up a quantity of ink far in excess of thatrequired, and it is common practice to employ a blade placed at an angleto the fountain roll to remove the extra ink. The fountain blade 24 issecured to the fountain back 32 which is itself secured to the fountainbowl 52 becoming a partial cover thereof. The plurality ofscrews 23threaded into the fountain back 62 is brought against the blade 24 forvthe purpose of adjusting clearance between said blade and the fountainroll 5I, thereby regulating the amount of ink supplied to the ductorroll 53.

Each screw 23 is made with a head 25a designed to accommodate a socket33 of an extension rod, part of the screw 23, that is carried in a guardI3. Said guard is composed of sections which are removable, each sectionbeing in alignment with a newspaper page. A spring '31 abutting theguard I3 and a collar 33 attached to the extension rod 23 causes thevsocket 33 to be held securely in place over a screw head 25a. A thumbscrew type head 25 on the screw 23 simplifies the screw adjustment.Therefore, it is evident that the removal of any section of the guard I3from the press will cause the screw 23 to be removed. It is commonpractice to make newspaper presses four pages wide, in which case therewould be four guard sections I9 per fountain back.

This is a desirable feature when using an auxiliary fountain for coloras shown in Fig. 9. Adjusting screws 23 may be used in shutting oil' theink supply for the page desired'and the guard section will be removed sothat a color fountain 1| can be bolted in position on the fountain back32, as shown.

A color fountain roll 10 is carried in the fountain 1I so that it ispartially submerged and rotates in the colored ink. A fountain blade 12is secured to a fountain back and cover 13. Adjusting screws 14 regulatethe amount of ink transferred to a ductor roll 15 rotatably mounted inthe end of lever arms 13. The ductor roll lever arm 16 is operated by acam 11 secured to a fountain roll drive shaft 3| and acting against acam roll 13 mounted in a lever arm 13. A spring 13 attached to said armand secured to the fountain back 13 holds the ductor roll 15 against thefountain roll 10. The cam action will cause the roll 15 to be movedagainst an ink drum 33 which will pick up the color from the ductor rolland distribute the ink film to the plate cylinder 3 through the regulardistribution system, already described.

A shaft 82 is connected to and rotates proportionally to the main drivethrough mechamsm not shown. Said shaft is made on one end in the form ofa clutch jaw 83 to engage a shaft 84. Mounted on the shaft 82 is a gear85 that operates a gear 86 to which is secured a bevel gear 81, and bothof which are carried by a shaft 88 mounted in suitable bearings 89. Thebevel gear 81 drives a gear 9| mounted on one end of a shaft 92. To theother end of the shaft 92 is fastened a gear 93 meshing with a gear 90secured to the shaft of the main fountain roll t is evident, therefore,that the operation of the press will cause the fountain roll 5| tooperate.

When using the auxiliary color fountain it is necessary to provide asuitable drive. The shaft 84 is carried by bearings 95 and 96 in acasing 91. Mounted on said shaft 84 is a helical gear 98 that drives agear v99. Said gear 99 is attached to a shaft 60 also carried in thecasing 91 by bearings 5| and 85. The shaft 60 extends beyond the casing91 and by a coupling 63 is connected to the auxiliary fountain rollshaft 8|. It should be noted that the casing 91 and its component partsmay be removed as a unit from the gear case 64 when the color fountainis not used and the opening in the casing 64 may be concealed by asuitable cover.

It is evident that a simple and suitable drive is obtained for usewith acolor fountain.

The adjusting screw extension rod guard |9 in Fig. 8 becomes |9a. |9b,and |9d in Fig. 12. Said guards are each individuallyl removable. Theguard.' which would be |9c and placed between the guards |9b and |9d hasbeen removed and replaced with an auxiliary ink fountain 1 I. Previousto removing the guard |'9c the adjusting screws 28 have been set to cutoi the ink supply in this section. It is also possible to prevent ink'from the main fountain from feeding by removing or setting off the mainductor roll 53. This would be preferred where the main fountain of thatparticular ink motion was not-to be used on any of the four pages.

When set in position,- theauxiliary fountain 1| is driven by the shaft8| through a driving collar |00, fastened thereon, cooperating with adriving plate |0| secured to the shaft 8| of the fountain roll 10. Anycombination of vone to four fountains may be added, the drive beingsecured by suitable change in the length of the shaft 8|.

In multiple arrangement, a plate |02 will become a driver similar to thecollar 55 and will cooperate with a plate'similar to the plate |0| onthe next fountain.

As shown, a margin screw |03 is not supplied with an extension rod asthis is infrequently adjusted. A suitable recess |04 is provided at thisposition to make it available for adjustment by a wrench, if necessary,and to allow adjustment in the event it is desired to do so.

It is apparent therefore that an apparatus is devised for optionallyinstalling one or more small page wide fountains by removing detachableparts of the main fountain back and that when this is accomplished, boththe main and auxiliary fountains are located on the same side of themain center line of the ink motion.

Having thus described our invention and the advantages thereof, we donot wish to be limited to the details herein disclosed, otherwise thanas set forth in the claims, but what we claim is:
